" LOCKING DEVICE.

Specification of Letters Patent. Patented Oct, 12,1915,

Application filed December 5, 1944. Serial No. 875,700.

To all whom it may concern:

Be it known that I, OSCAR 'V. PAYNE, a citizen of the United States,residing at Takoma Park, in the county of- Montgomery improvements inlocking devices, and has" relation 'more particularly to a device orthis general character, wherein a collar is" locked to a shank or thelike, and an object of the invention is to provide a novel and improvedlocking'device whereby the collar and shank may be held against relativer05 tation. V V v v It is also an object of my invention'topro vide anovel and improved locking devicecomprising a collar having upon a facethereof channels placed at predetermined positions and adapted toreceive a pliable key held in a transverse cavity ofa shanky said keybeing adapted to prevent relative rotation of the collar and shank.

One of the novel features of my inven tion is that the collar may belockedat any point of its axial rotation upon its shank,

since there are no registering parts when the collar 1s 1n a lockedposition; and another novel feature of my improved device is that thecollar is locked in the position last assumed, backing-ofwnot beingnecessary.

This invention consists in the details of construction and in thecombination and arrangements of the several parts of'my improved lockingdevice, whereby certain important advantages are attained, and thedevice is rendered simpler, less expensive, and otherwise moreconvenient and advantageous for use, all as will be hereinafter morefully set forth.

.The novel features of my invention will be carefully defined in theappended claims. In order that my invention may be better understood, Iwill now proceed to describe the same with reference to the accompanyingdrawing, wherein like reference characters designate correspondingparts, and in which I Figure 1 is a top plan view of an embodiment of myinvention, showing the pro ections of the collar in position to receivethe pliable key, which is adapted to hold them in locked position. Fig.2 is a view similar to Fig. 1, showing the collar turnec home andlocked.Fig 3' is a sectional view taken substantially on the line 3'3 of Fig.2. Fig; 4 is a top plan view similar to Fig. 1, showing my inventionapplied to the conventional threaded "bolt and nut. Fig; 5 is asectional view taken substantially on; the

line 55 of'Fig. 4. I 7

As described in Figs. 1 to 3, A designates a'shank of any ordinary orpreferred construction, having a transverse channel or cavity 1, whichmay. b of a 'cQnfigumtion.

to suit the necessary requirements, said cavity or channel being hereindisclosed as a hole produced in an end of the shank. Adapted to surroundthe shank A, is the collar B, having upon a face thereof the projections2, placed at predetermined intervals and affording the cavities orchannels 3, which are adapted to receive the extremities of the pllablekey 4, when said key is in appliedp'o sitio-n. To look the collar B tothe shank1A,

position the pliable key 4 in the cavity or channel '1 of the shank A"with the extremities thereof within the cavities orchannels 4 of thecollar B, as is illustrated in Fig.1; As is thought to be obvious, uponthe relative rotation of the shank and collar, the pliable key 4 "willbe drawn through "the? cavities or channels alforded by the projections2 and brought'in contact with, and partly embracing, the shank A, as isshown in Fig. Since the pliable qualities ofv the key are exempt fromall vibratory infiu ences, the collar can be removed only by returningthe collar B to its original position with relation to the shank A.

In Figs. 1 to 3, 'I have shown the shank A as smooth and unobstructed,as I have found in practice with thisarrangement' my invention operateswith facility, but I also intend that my invention be employed to lock abolt and a co-acting nut, as is shown in Figs. 4 and 5, wherein theconstruction and arrangement of the various parts are substantiallyidentical to what has been previously described, and for this reason Ihave applied to Figs. 4 and 5, the same reference characters as appliedto the preceding fig-. ures. In this form of my invention, however, itis to be noted that the intermediate portion of the key'4 is receivedwithin the threads 5 of the bolt A.

Any tool which can be used to manipulate the collar, is the only toolnecessary to lock or remove the collar from its shank. The

pliable locking key may vary'in size inasmuch as precision is notnecessary in thechannels-of the collar upon relative rotamanufacturingof my locking device.-

The extremely simple construction employed in the manufacture of mylocking device makes economy an important feature of my invention.

.From the foregoing description it is thought to be obvious thatalocking device constructed in accordance with my invention is of anextremely simple and comparatively' inexpensive nature, and isparticularly Well adapted for use by reason of the convenience andfacility with which it may be assembled, and it will alsobe obvious thatmy invention is susceptible of some change and modification withoutmaterial departure from the principles and spirit thereof, and for thisreason I do not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingout my invention in practice, except as is defined by the scopeof theclaims appended hereto.

What I claim, is:

1. In combination with a shank having a cavity disposed transverselythereof, a collar adapted to surround the shank, said collar beingprovided with spaced channels positioned at predetermined intervalstransversely thereof and having their inner extremities spaced from thebore of said collar, and a pliable key adapted to be inserted throughthe cavity of the shank With its extremities positioned withinthechannels of the collar.

2. In combination with a shank having a cavity disposed transverselythereof, a collar adapted to surround the shank, said collar beingprovided with spaced channels positioned at predetermined intervalstransversely thereof and having their inner extremities spaced from thebore of said collar, and a pliable key adapted to be inserted throughthe cavity with its extremities positioned Within the spaced channels ofthe col lar, saidkey being of such a length as to Copies of this patentmay be obtained for five cents each, by addressing the maintainits'extremities within the spaced tionof said shank and collar.

3. In combination with a shank having a cavity disposed transverselythereof, a collar adapted to surround the shank, said shank and collarbeing capableof relative axial rotation said collar being provided withchannels having their inner extremities spaced from the bore of saidcollar, said channels of the collar and the cavity of the shank beingadapted to initially register, and a pliable key inserted in the cavityand Within the channels when said cavity and channels are in register.

4. In combination with a shank having a cavity disposed transverselythereof, a collar adapted to surround the shank, said shank and collarbeing capable of relative axial rotation, said collar being providedwith channels having their inner extremities spaced from the bore ofsaid collar, said channels of the collar and cavity of the shank beingadapted to initially register, and a pliable key inserted in the cavityand within the channels when said cavity and channels are in register,said key being adapted to be flexed exteriorly of the shank uponrelative rotation of the shank and collar.

5. In combination with a threaded shank having a cavity disposedtransversely thereof, a nut adapted to coact with said shank, said nutbeing provided with spaced projections on a face thereof, and a pliablekey adapted to be positioned within the cavity of the shank and betweenthe projections of the nut, said projections being so positioned as toforce the key in close proximity with the threads of the shank uponrelative rotation of the shankand nut.
